RAILJOINT.

Application filed May 23. 1912.

To all whom it may concern Be it known that I. ALBER Kt'nmwsnnv. citizenof the United States, residing at Xanticoke, in the county of Luzerncand State of Pennsylvania. have invented certain new and usefulImprovements in Rail- Joints, of which the following is a specification.

This invention relates to improvements in rail joints, and has for oneof its objects to improve the construction and increase the efficiencyand utility of devices of this character.

Another object of the invention is to provide a device of this characterhaving relatively small internal engagement, while at the same timecapable of producing a very stiff and rigid joint.

Another object of the invention is to provide a simply constructeddevice whereby broken or impaired parts may be readily replaced withcrltdisturbing the other rails.

Another object of the invention is to provide' a simply constructeddevice whereby provision is made for taking up slack in the joint andrigid! uniting the parts, and whereby wear 111 y be taken up withoutdisturbing the joint or separating the parts.

Another object of the invention is to provide a rail joint having theparts interchangeable or with the rails reversible end for end.

\Vith these and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and de scribed, andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention.

Figure 1 is a side elevation of the confronting ends of a pair of railsconstructed in accordance with the invention; Fig. 2 is a plan view ofthe parts shown in Fig. 1; Fig. 3 is an end elevation of one of therails; Fig. 4 is a perspective view of one of the rails at one end; Fig.5 is a view in section on the line 55 of Fig. 1; Fig. 6 is a viewsimilar to Fig. 2 illustrating a modification in the construction; Fig.7 is a transverse section on the line 77 of Fig. 6. Fig. 8 is aperspective view of one of the rails at one end illustrating themodified form shown in Fig. 6; Fig. 9 is a section on the line 9-9 ofFig. 7; Fig. 10 is a perspective view of the supporting base or chairemployed in the modified structure shown in Figs. 1 to 5.,

Specification of Letters Patent.

Serial No. 699,277.

Figs. 6. 7, 8 and 9; Fig. 11 is a sectional detail illustrating anotherslight modification it: he construction.

Corr. ponding and like parts are referred to in th following descriptionand indicated in all tl. views of the drawings by the same referencecharacters.

The body portions of the rails are of the usual form and of the usuallength and comprise .the tie flanges 10, vertical webs "11 and heads 12,and may be of any required dimensions. At their terminals the rails arereduced or cutaway atone side as in the structure shown in Figs. 2 to 4,the inner face 13 of the cutaway port-ions inclined 0bliquely, while inthe structure shown in Figs. 6, 7 and S, the inner face 14 of thecutaway portion extends in the same longitudinal plane as the rail. Bythis means a transverse shoulder 15 is produced at the inner terminal ofthe inclined portions 13 and 14. The vertical web 11 is increased inthickness at the inner end of the inclined portionas represented at 16,and a cavity represented at 17 formed in the thickened portion of theweb and opening outwardly or toward the end of the rail. The thickenedportion of the vertical web is extended at one side in the form of atongue 18 and projection beyond the terminal of the reduced portion. Theprojecting portion of the tongue is reduced in thickness as representedat 19 and preferably with its sides converging toward the upper edge, asshown.

In the structure disclosed in Figs. 1 to the inner face of the tongue 18is inclined obliquely to the longitudinal plane of the rail andreversely to the inclined face 13 of the reduced portion, as shown,while in the structure disclosed in Figs. 6, 7, 8 and 9 the inner faceof the tongue extends parallel to the face 11, or in the samelongitudinal plane as the rail. A tapered aperture is formed through thethickened portion of each vertical web and communicates with the recessor cavity 17 the lower half of the aperture being formed in the bottomof the recess. The tapered aperture is designed to receive a taperedbolt 20 having a keyway to receive a split key 21. The larger end of thebolt 20 extends from one side of the thickened portion 16 of thevertical web, while the kev 21 bears against the opposite side of thethickened portion.

In the form of the structure illustrated in the tongue 18 is providedwith spaced longitudinally slotted apertures 22 to receive clamp boltsand the projecting portion of the tongue is provided with a slottedtransverse cavity 24 to receive the tapered bolt 20. v

In the modification shown in Figs. (3, 7. 8

and 9 the tongue 18 is .shorter than in the is employed beneath thejoint portion of the rails and bearing upon the tie. The plate 28 isprovided with upwardly directed stop ribs 29 to bear against theopposite edges of the tie flange. The chair or tie plate 28 is alsoprovided with an upstanding stud 30 to enter the cavity 25 and taperedto correspond to the taper-of the cavity. By this means the stud 30bears by its ends against the shoulders 26 of the rails, and firmlyunites and locks the parts in position and prevents lateraldisplacement. When the construction shown in Figs. 6 and 9 is employed,no transverse bolts are required through the vertical webs, but in lieuof such holding devices tap screws 31 or like devices'are employed tobind the railsto the chair and to the tie.

The improved device issimple in'con-' struction, is strong and durable,and so arranged that the parts mutually coact to reinforce each other sothat all lateral displacement is eflectually prevented, and the partsfirmly held and united. By this arrangement also the parts comprisingthe joint may be readily tightened in event of their working loose aswill be obvious.

In the structure shown in Figs. 6, 7, 9and 10 one of the tap screws 31only is employed in engagement with the rails to prevent creeping whilepermitting the movement produced by the usual expansion and contraction.

In Fig. 11 a slight modification is shown in the construction consistingin forming the tongue 18 shorter and wedge-shaped at its terminal andfitting in a relatively short recess 17. This construction may beemployed under certain circumstances if required.

Having thus described the invention, what is claimed as new is:

1. A railway rail reduced laterally at the ends and with a cavity in thebody of the rail at the juncture therewith of the reduced portion andwith a tongue extending beyond the reduced portion, said rail havingtransends and with a cavity in the body of the rail at the juncturetherewith of the reduced portion and with a tongue extending beyond thereduced portion, each of said reduced portions having an intermediaterecess, whereby when the rails are united end to end the reducedportions will engage face to face and the tongues enter the cavities,and a chair member bearing beneath the rails and provided with a studfor engaging in the intermediate recesses.

3. A railway rail reduced laterally at the ends and with a cavity in thebody of the rail at the juncture therewith of the reduced portion andwith a tongue extending beyond the reduced portion, each of said reducedportions having an. intermediate recess, said rail having transverselyalined apertures communicating with the cavities and said tongues havingtransverse recesses, fasten; ing devices adapted to operate through thealincd apertures of the cavities and the re cesses of the tongues. and achair member bearing beneath said rails and provided with a stud forengaging in the intermediate recess.

In testimony whereof I affix my signature in presence of two witnesses.
